config BCM47XX_NVRAM
bool "Broadcom NVRAM driver"
depends on BCM47XX || ARCH_BCM_5301X
help
Broadcom home routers contain flash partition called "nvram" with all
important hardware configuration as well as some minor user setup.
NVRAM partition contains a text-like data representing name=value
pairs.
This driver provides an easy way to get value of requested parameter.
It simply reads content of NVRAM and parses it. It doesn't control any
hardware part itself.
config BCM47XX_SPROM
bool "Broadcom SPROM driver"
depends on BCM47XX_NVRAM
help
Broadcom devices store configuration data in SPROM. Accessing it is
specific to the bus host type, e.g. PCI(e) devices have it mapped in
a PCI BAR.
In case of SoC devices SPROM content is stored on a flash used by
bootloader firmware CFE. This driver provides method to ssb and bcma
drivers to read SPROM on SoC.

Subject: [PATCH] ARM: BCM5310X: activate erratas needed for SoC
The BCM4708 I have, which is probably the first generation which got
to the consumer market, is using a ARM Cortex-A9 rev r3p0 and a
L2C-310 rev r3p2 L2 cache controller. There are 3 workarounds for known
erratas in the Linux kernel which could be activated and will be in
this patch. There are currently no workarounds which have to be
activated for the L2C-310 rev r3p2 in Linux.

Subject: [PATCH 1/2] PCI: iproc: Allow override of device tree IRQ mapping
function
The iProc core PCIe driver defaults to using of_irq_parse_and_map_pci() for
IRQ mapping. Add iproc_pcie.map_irq so bus interfaces that don't use
device tree can override this by supplying their own IRQ mapping function.

Subject: [PATCH 2/2] PCI: iproc: Add BCMA PCIe driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This driver adds support for the PCIe 2.0 controller found on the BCMA bus.
This controller can be found on (mostly) all Broadcom BCM470X / BCM5301X
ARM SoCs.
The driver found in the Broadcom SDK does some more stuff, like setting up
some DMA memory areas, chaining MPS and MRRS to 512 and also some PHY
changes like "improving" the PCIe jitter and doing some special
initialization for the 3rd PCIe port.
This was tested on a bcm4708 board with 2 PCIe ports and wireless cards
connected to them.
PCI_DOMAINS is needed by this driver, because normally there is more than
one PCIe controller and without PCI_DOMAINS only the first controller gets
registered. This controller gets 6 IRQs; the last one is trigged by all
IRQ events.

Subject: [PATCH 2/2] PCI: iproc: Free resource list after registration
The resource list is only used in the setup process and was never freed.
pci_add_resource() allocates a memory area to store the list item.
Fix the memory leak.

Subject: [PATCH] PCI: iproc: Delete unnecessary checks before phy calls
The functions phy_exit() and phy_power_off() test whether their argument is
NULL and then return immediately. Thus the test around the calls is not
needed.
This issue was detected by using the Coccinelle software.
[bhelgaas: also phy_init() and phy_power_on(), as Ray Jui suggested]

Subject: [PATCH 1/4] PCI: iproc: enable arm64 support for iProc PCIe
PCI: iproc: Add arm64 support
Add arm64 support to the iProc PCIe driver.
Note that on arm32, bus->sysdata points to the arm32-specific
pci_sys_data struct, and pci_sys_data.private_data contains the
iproc_pcie pointer. For arm64, there's nothing corresponding to
pci_sys_data, so we keep the iproc_pcie pointer directly in
bus->sysdata.
In addition, arm64 does IRQ mapping in pcibios_add_device(), so it
doesn't need pci_fixup_irqs() as arm32 does.

Subject: [PATCH 4/7] PCI: iproc: Fix PCIe reset logic
The current reset logic does not always properly reset the device. For
example, in the case when the perst_b signal is already de-asserted in the
bootloader, the current reset logic fails to trigger a proper assert ->
de-assert reset sequence.
Fix the issue by always triggering the proper reset sequence.
Also explicitly select the desired reset source, i.e., perst_b, and reduce
the wait time after the device comes out of reset from 250 ms to 100 ms,
based on recommendation from the ASIC team.

Subject: [PATCH] PCI: iproc: Hide CONFIG_PCIE_IPROC
PCIE_IPROC_BCMA does not require CONFIG_OF in Kconfig, but
CONFIG_PCIE_IPROC does, so we can get a warning when building for an ARM
platform without DT support:
warning: (PCIE_IPROC_PLATFORM && PCIE_IPROC_BCMA) selects PCIE_IPROC which has unmet direct dependencies (PCI && OF && (ARM || ARM64))
It turns out that CONFIG_PCIE_IPROC never needs to be enabled by a user
anyway, we can simply rely on it being selected implictly through either
PCIE_IPROC_PLATFORM or PCIE_IPROC_BCMA.

Date: Fri, 4 Dec 2015 09:34:59 -0800
Subject: [PATCH 2/5] PCI: iproc: Add PAXC interface support
Traditionally, all iProc PCIe root complexes use PAXB-based wrapper, with
an integrated on-chip Serdes to support external endpoint devices. On
newer iProc platforms, a PAXC-based wrapper is introduced, for connection
with internally emulated PCIe endpoint devices in the ASIC.
Add support for PAXC-based iProc PCIe root complex in the iProc PCIe core
driver. This change factors out common logic between PAXB and PAXC, and
uses tables to store register offsets that are different between PAXB and
PAXC. This allows the driver to be scaled to support subsequent PAXC
revisions in the future.

Subject: [PATCH 4/5] PCI: iproc: Add iProc PCIe MSI support
Add PCIe MSI support for both PAXB and PAXC interfaces on all iProc-based
platforms.
The iProc PCIe MSI support deploys an event queue-based implementation.
Each event queue is serviced by a GIC interrupt and can support up to 64
MSI vectors. Host memory is allocated for the event queues, and each event
queue consists of 64 word-sized entries. MSI data is written to the lower
16-bit of each entry, whereas the upper 16-bit of the entry is reserved for
the controller for internal processing.
Each event queue is tracked by a head pointer and tail pointer. Head
pointer indicates the next entry in the event queue to be processed by
the driver and is updated by the driver after processing is done.
The controller uses the tail pointer as the next MSI data insertion
point. The controller ensures MSI data is flushed to host memory before
updating the tail pointer and then triggering the interrupt.
MSI IRQ affinity is supported by evenly distributing the interrupts to each
CPU core. MSI vector is moved from one GIC interrupt to another in order
to steer to the target CPU.
Therefore, the actual number of supported MSI vectors is:
M * 64 / N
where M denotes the number of GIC interrupts (event queues), and N denotes
the number of CPU cores.
This iProc event queue-based MSI support should not be used with newer
platforms with integrated MSI support in the GIC (e.g., giv2m or
gicv3-its).

From 46560388c476c8471fde7712c10f9fad8d0d1875 Mon Sep 17 00:00:00 2001

Subject: [PATCH] PCI: iproc: Allow multiple devices except on PAXC
Commit 943ebae781f5 ("PCI: iproc: Add PAXC interface support") only allowed
device 0, which is a regression on BCMA-based platforms.
All systems support only one device, a Root Port at 00:00.0, on the root
bus. PAXC-based systems support only the Root Port (00:00.0) and a single
device (with multiple functions) below it, e.g., 01:00.0, 01:00.1, etc.
Non-PAXC systems support arbitrary devices below the Root Port.
[bhelgaas: changelog, fold in removal of MAX_NUM_PAXC_PF check]
Fixes: 943ebae781f5 ("PCI: iproc: Add PAXC interface support")

Subject: [PATCH] ARM: BCM5301X: Ignore another (BCM4709 specific) fault code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Broadcom ARM devices seem to generate some fault once per boot. We
already have an ignoring handler for BCM4707/BCM4708, but BCM4709
generates different code.

RT-AC87U
The NAND flash chip description were not imported for the Asus RT-AC87U
dts file when this was done for all the other dts files, because these
patches were send in parallel.
This adds a missing NAND flash chip description to this patch:

Subject: [PATCH 70/74] ARM: l2c: restore the behaviour documented above
l2c_enable()
l2c_enable() is documented that it must not be called if the cache has
already been enabled. Unfortunately, commit 6b49241ac252 ("ARM: 8259/1:
l2c: Refactor the driver to use commit-like interface") changed this
without updating the comment, for very little reason. Revert this
change and restore the expected behaviour.

the auxiliary control register first, so that bits shared with other
registers (such as the prefetch control register) are not overwritten
by the later write to the auxctrl register.

Subject: [PATCH 72/74] ARM: l2c: clean up l2c_configure()
l2c_configure() does not follow the pattern of other l2c_* functions.
Fix this so that it does to avoid future confusion.

Subject: [PATCH 73/74] ARM: l2c: only unlock caches if NS_LOCKDOWN bit is set
Some L2C caches have a bit which allows non-secure software to control
the cache lockdown. Some platforms are unable to set this bit. To
avoid receiving an abort while trying to unlock the cache lines, check
the state of this bit before unlocking. We do this by providing a new
method in the l2c_init_data to perform the unlocking.

Subject: [PATCH 74/74] ARM: l2c: avoid passing auxiliary control register
through enable method
Avoid passing the auxiliary control register value through the enable
method. In the resume path, we have to read the value stored in
l2x0_saved_regs.aux_ctrl, only to have it immediately written back by
l2c_enable(). We can avoid this if we have __l2c_init() save the value
directly to l2x0_saved_regs.aux_ctrl before calling the specific enable
method.

Subject: [PATCH 1/4] ARM: l2c: Add support for the "arm, shared-override"
property
"CoreLink Level 2 Cache Controller L2C-310", p. 2-15, section 2.3.2
Shareable attribute" states:
"The default behavior of the cache controller with respect to the
shareable attribute is to transform Normal Memory Non-cacheable
transactions into:
- cacheable no allocate for reads
- write through no write allocate for writes."
Depending on the system architecture, this may cause memory corruption
in the presence of bus mastering devices (e.g. OHCI). To avoid such
corruption, the default behavior can be disabled by setting the Shared
Override bit in the Auxiliary Control register.
Currently the Shared Override bit can be set only using C code:
- by calling l2x0_init() directly, which is deprecated,
- by setting/clearing the bit in the machine_desc.l2c_aux_val/mask
fields, but using values differing from 0/~0 is also deprecated.
Hence add support for an "arm,shared-override" device tree property for
the l2c device node. By specifying this property, affected systems can
indicate that non-cacheable transactions must not be transformed.
Then, it's up to the OS to decide. The current behavior is to set the
"shared attribute override enable" bit, as there may exist kernel linear
mappings and cacheable aliases for the DMA buffers, even if CMA is
enabled.
See also commit 1a8e41cd672f894b ("ARM: 6395/1: VExpress: Set bit 22 in
the PL310 (cache controller) AuxCtlr register"):
"Clearing bit 22 in the PL310 Auxiliary Control register (shared
attribute override enable) has the side effect of transforming
Normal Shared Non-cacheable reads into Cacheable no-allocate reads.
Coherent DMA buffers in Linux always have a Cacheable alias via the
kernel linear mapping and the processor can speculatively load
cache lines into the PL310 controller. With bit 22 cleared,
Non-cacheable reads would unexpectedly hit such cache lines leading
to buffer corruption."

Subject: [PATCH 3/3] ARM: BCM5301X: activate some additional options in pl310
cache controller
In the default Broadcom SDK the shared override is activated for this
cache controller, do the same in the upstream code. Data and
instruction prefetching is not activated by default for this cache
controller on the bcm53xx SoC, do it manually like it is done in the
vendor SDK.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There are two possible UARTs so we have (both of) them disabled by
default. Override uart0 status on devices that were verified to use it.
In case of Netgear R6250 also drop an old (and invalid) overwrite. It
doesn't have uart1 connected.

Add device tree files for Broadcom Northstar based SVKs. Since the
bcm5301x.dtsi already exists, all that is necessary is the dts files to
enable the UARTs. With these files, the SVKs are able to boot to shell.

Subject: [PATCH 20/32] mtd: nand: add common DT init code
These are already-documented common bindings for NAND chips. Let's
handle them in nand_base.
If NAND controller drivers need to act on this data before bringing up
the NAND chip (e.g., fill out ECC callback functions, change HW modes,
etc.), then they can do so between calling nand_scan_ident() and
nand_scan_tail().

Subject: [PATCH 130/134] dt-bindings: add SMP enable-method for Broadcom NSP
Add a compatible string "brcm,bcm-nsp-smp" for Broadcom's
Northstar Plus CPU to the 32-bit ARM CPU device tree binding
documentation file and create a new binding documentation for
Northstar Plus CPU.

+Broadcom Northstar Plus SoC CPU Enable Method
+---------------------------------------------
+This binding defines the enable method used for starting secondary
+CPUs in the following Broadcom SoCs:
+ BCM58522, BCM58525, BCM58535, BCM58622, BCM58623, BCM58625, BCM88312
+
+The enable method is specified by defining the following required
+properties in the "cpus" device tree node:
+ - enable-method = "brcm,bcm-nsp-smp";
+ - secondary-boot-reg = <...>;
+
+The secondary-boot-reg property is a u32 value that specifies the
+physical address of the register which should hold the common
+entry point for a secondary CPU. This entry is cpu node specific
+and should be added per cpu. E.g., in case of NSP (BCM58625) which
+is a dual core CPU SoC, this entry should be added to cpu1 node.
+
+
+Example:
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ enable-method = "brcm,bcm-nsp-smp";
+
+ cpu0: cpu@0 {
+ device_type = "cpu";
+ compatible = "arm,cortex-a9";
+ next-level-cache = <&L2>;
+ reg = <0>;
+ };
+
+ cpu1: cpu@1 {
+ device_type = "cpu";
+ compatible = "arm,cortex-a9";
+ next-level-cache = <&L2>;
+ reg = <1>;
+ secondary-boot-reg = <0xffff042c>;
+ };
+ };

Subject: [PATCH 133/134] ARM: BCM: Add SMP support for Broadcom NSP
Add SMP support for Broadcom's Northstar Plus SoC
cpu enable method. This changes also consolidates
iProc family's - BCM NSP and BCM Kona, platform
SMP handling in a common file.
Northstar Plus SoC is based on ARM Cortex-A9
revision r3p0 which requires configuration for ARM
Errata 764369 for SMP. This change adds the needed
configuration option.

Subject: [PATCH] USB: bcma: remove chip id check
I have never seen any bcma device with an USB host core which was not a
SoC, the bcma devices have an USB device core with a different core id.
Some SoC have IDs with 47XX and 53XX in decimal form which would be
rejected by this check. Instead of fixing this check just remove it.

Subject: [PATCH V2] USB: bcma: switch to GPIO descriptor for power control
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
So far we were using simple (legacy) GPIO functions & some poor logic to
control power. It got many drawbacks: we were ignoring OF flags
(GPIO_ACTIVE_LOW), we were not setting direction to output and we were
assuming gpio_request success all the time.
Fix it by switching to gpiod functions and adding appropriate checks.

Subject: [PATCH v3 1/6] usb: xhci: plat: fix adding usb3-lpm-capable quirk
The xhci->quirks member is overwritten in xhci_gen_setup() with the
quirks given through the module load parameter. Without this patch the
usb3-lpm-capable quirk will be over written before it gets used. This
patch moves the quirks code to the xhci_plat_quirks() callback function
which gets called directly after the quirks member variable is
overwritten with the module load parameter.
I do not have any hardware which is using usb3-lpm-capabls so I can not
test this on real hardware.

This fixes problem with controller seeing devices only in some small
percentage of cold boots.
This quirk is also added to the platform data so we can activate it
when we register our platform driver.

Subject: [PATCH] ARM: BCM5301x: Disable MMU and Dcache during decompression
Date: Tue, 14 Jul 2015 16:12:08 -0700
Use the existing __armv7_mmu_cache_flush() to perform the cache flush
since this does what we are after.

Subject: [PATCH] bgmac: add support for the 3rd bus core (device)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
So far we were supporting up to 2 cores but recent devices (e.g. Netgear
R8000) may use 3rd as well. Lower ones (1st, 2nd) are usually used for
some offloading then.

Subject: [PATCH] ARM: BCM5310X: activate erratas needed for SoC
The BCM4708 I have, which is probably the first generation which got
to the consumer market, is using a ARM Cortex-A9 rev r3p0 and a
L2C-310 rev r3p2 L2 cache controller. There are 3 workarounds for known
erratas in the Linux kernel which could be activated and will be in
this patch. There are currently no workarounds which have to be
activated for the L2C-310 rev r3p2 in Linux.

Subject: [PATCH 45/50] clk: iproc: Add PWRCTRL support
Some iProc SoC clocks use a different way to control clock power, via
the PWRDWN bit in the PLL control register. Since the PLL control
register is used to access the PWRDWN bit, there is no need for the
pwr_base when this is being used. A new flag, IPROC_CLK_EMBED_PWRCTRL,
has been added to identify this usage. We can use the AON interface to
write the values to enable/disable PWRDOWN.

All writes to the PLL base address must be flushed if the

necessary write and reads, we can make sure that any future code which
makes PLL base writes will do the correct thing.

Subject: [PATCH 48/50] clk: iproc: Split off dig_filter
The PLL loop filter/gain can be located in a separate register on some
SoCs. Split these off into a separate variable, so that an offset can
be added if necessary. Also, make the necessary modifications to the
Cygnus and NSP drivers for this change.

Subject: [PATCH 49/50] clk: iproc: Separate status and control variables
Some PLLs have separate registers for Status and Control. The means the
pll_base needs to be split into 2 new variables, so that those PLLs can
specify device tree registers for those independently. Also, add a new
driver flag to identify this presence of the split, and let the driver
know that additional registers need to be used.

Subject: [PATCH] ARM: BCM5301X: add NAND flash chip description for Asus
RT-AC87U
The NAND flash chip description were not imported for the Asus RT-AC87U
dts file when this was done for all the other dts files, because these
patches were send in parallel.
This adds a missing NAND flash chip description to this patch:

Subject: [PATCH] ARM: dts: bcm5301x: Add BCM SVK DT files
Add device tree files for Broadcom Northstar based SVKs. Since the
bcm5301x.dtsi already exists, all that is necessary is the dts files to
enable the UARTs. With these files, the SVKs are able to boot to shell.
